Special Weed Problems

(Reviewed 12/09, updated 12/09)

In this Guideline: More about weeds in caneberries:

Field bindweed and yellow nutsedge are the primary species that are most difficult to control in caneberry plantings. While they are best controlled with soil fumigation before planting, if they are still present after planting, a program is needed for their control. Possible control strategies include spot treatments with glyphosate and handweeding.

Do not allow perennial weeds to reestablish and produce vegetative propagules. Tubers of yellow nutsedge can remain viable in the soil for up to 3 years. Preventing aboveground establishment of perennial weeds assures that belowground vegetative reproduction parts are not replenished with carbohydrates. With every germinating shoot, carbohydrate reserves are utilized; thus, long-term timely control of aboveground parts will eventually deplete the resources of established perennial weeds. This approach may not be feasible where high densities of perennial weeds are present and pre-plant soil fumigation is justified.
